Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R . Assertion A : Experimental reaction of CH 3 Cl with aniline and anhydrous AlCl 3 does not give o and p -methylaniline. Reason R : The - NH 2 group of aniline becomes deactivating because of salt formation with anhydrous AlCl 3 and hence yields m -methyl aniline as the product. In the light of the above statements, c

Step-by-step solution

Under the Friedel Craft Reaction condition, the aniline (a Lewis base) binds to the electrophile   AlCl 3 (a Lewis acid) to give a coordination complex (a salt). Then, the positive charge on the nitrogen is electron withdrawing, and it pulls the electron density of the aromatic ring by - I   effect . It therefore, deactivates the ring for further alkylation reactions. Finally, the complex precipitates out of the reaction mixture and the alkylation reaction is not observed.
